Question

Researchers investigated two kinds of laugh tracks – one with posed laughter and one with spontaneous laughter. Recall that to create the posed laughter laugh track, the researchers asked people to laugh and recorded the results. The researchers also tested the same 40 jokes with a spontaneous laughing laugh track, which they created by having people watch funny videos and recording their laughter. The data can be found in the file LaughTypes in pictures. Put these data into the Matched Pairs applet to investigate whether the type of laughter makes a difference in the ratings of the jokes and also do parts (a) (b) and (c):

(a) State the relevant hypotheses in words.
O Null: The type of laughter has no effect on the rating of the joke.
Alt: The type of laughter does have an effect on the rating of the joke.
ONull: The type of laughter does have an effect on the rating of the joke.
Alt: The type of laughter has no effect on the rating of the joke.
Null: The type of laughter has no effect on the rating of the joke, on average.
Alt: The type of laughter does have an effect on the rating of the joke, on average.
O Null: The type of laughter does have an effect on the rating of the joke, on average.
Alt: The type of laughter has no effect on the rating of the joke, on average.
